This invention relates to animproved construction of spectacle temples; and has for its, object to construct such a temple with a wire core member covered with a non-metallic tube and to provide an enlargement on the end of the core where it projects beyond the tube to lock the tube on the core and to fit a cap member on the end of the tube to house the core enlargement and provide a finish for t e end of the tube, a

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described,

and particularly pointed out in the appended claims. V

In the accompanying drawings:

Figure 1 is a side elevation showing a'portion'of a temple having a wire core covered Figure 3 is a short length ofv n0n-metallic tubing designed tofit over the metallic wire core. c a

Figure 4 is a perspective view of a cap designed to fit, onto the end of the tube and house the enlarged end of the wire core.

Figure 5 is a perspective view of a collar or Washer to rest against the end of the tube.

I the core to protect this end from' corrosion Figure G is a sectional end view of the core as extending beyond theend of the-tubing and the cap fitted on the end of the tubing to -house the end of the core and the washer.

Figure 7 is a sectional end View on line 7-7 character that where the wire core is covered with a' non-metallic tube it is of advantage to extend the core beyond the tube and enlarge its end to lock thetube on the core and in such cases it isfound of advantage toprovide a capor cover'for the projecting end of and make a finish for the end of the tube; and the following is a detailed description of the present embodimentof my invention and showing one, construction bywhich these advantageous results may be accomplished With reference to. the drawings, 10 desig-Yt nates the Wire coreof a templeover which a. non-metallic tubing ll is passed, the ear: engaging loop portion 13 of the tubing being formed eitherv plain or cut helically, as, illus-' trated in Figures land V f In order to secure'the looped end of -the I tubing. on its wire core, I preferably extend the wire core beyond the end 143 of the tub ing, as illustrated in Figure 6, and in some cases I preferably pass a metallic washer 15 over the end of the coreto rest against the end 14 of the tubing and then flatten and so enlarge or extend the end 16 of this wire .core, which enlarged portion presses the washer against the end of the tube and locks v the tube in place on the wire core.

As it would not be practical to leave the inetallic'end of the core exposed,I have pro-- vided a simple and effective way for housing the same which is that of providing a cap 17 which has a bore 18 to fit over theend of the tube,,the bore being of a size to receive and house the washer 15 and also the enlarged end 15'of the Wire core. In some instances, it is found of advantage to reduce the neck portion'19 of this cap member down to meet the surface of the tube as at 20, or

any other desired finish may be provided for a this cap. In some instances, it is found of advantage to drill a vent hole" 21' in the end of the cap to permit the escape of air when the capis forced'into positionon theend of the tube whereit may 'becemented in place. This cap orend piecemay be formed in any desired shape, in some cases it may be substantially the size of the tubing itself, while in still other cases it may be enlarged beyond the diameter of the tube to form the desired finish on the end thereof. 7

'My improved construction of, temple is. very simple and inexpensive to manufacture and will well serve the purpose of housing the projecting metal parts covering them from sight and preventing "corrosion of the .ly towards the construction illustrated,- but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim v 1. A spectacle temple formed of a Wire core covered with a non-metallic tube, means at the end of the tube for locking the tube w to the wire, and an enlarged non-metallic cap having a bore to receive the end of the tubeand the locking means to cover the same, the contacting surfaces of said end piece and tube being of non-metallic material and cemented together.

2. A spectacle temple formed of a wire core coveredwith a celluloid tube, means at the endof the tube for locking the tube to the wire, and an enlarged celluloid. cap having a bole to receive the end of the tube and the locking means to cover the same, the contacting surfaces of said end piece and tube being of celluloid material and cementeditogetwher by softening the contacting surfaces. Intestimony whereof I aflix my signature.
